The full Thai name of the two beetles is ดวงหนวดยาวพิกุล
The first part of this long name, namely ดวงหนวดยาว, means longhorned beetle and indicates the name of the family to which it belongs (longhorn beetles = cerambycidae). The second part of the name, พิกุล, is the name of a large tree scientifically named Misumops elengi or Iroon Wood Tree or Bullet Tree. This tree has valuable timber and edible fruits. The beetle is regarded as a pest to this tree. The female lays eggs on the bark of this tree, after 7 days the larvae hatch from these eggs and  immediately begin to bore into the wood and destroy it. In British Malaya the beetle was therefore called Misumops stem borer.
The beetle is found from Iran to Borneo…and very often in Thailand. Already in the mid of the 19^th century it was described and scientifically named by British entomologist John O. Westwood.

The two trees, “Ceiba petandra” and “Bombax ceiba” are very close to each other. Some botanists suggest even that they belong to one single genus, namely Bombax.

In Thai language the first tree is called ต้นงี้ว,  the second one is called ต้นนุ่น.

Although the two trees are very similar to each other, they can be distinguished amongst others by the form of their pods: in Bombax ceiba the ratio width : length is between 1:4 to 1:3,  in Ceiba (or Bombax) petandra this ratio is about 1:5.

To judge from the pictures the tree must be Bombax ceiba.

In Malay language the silk-like fibers in the pod are called kapuk, from which the words kapok and – found somethat scarcer I believe- kopak are derived. Kapok and kopak are synonyms. Thus a kapok tree and a kopak tree would be the same. The true kapok/kopak tree is only Ceiba pentandra, but mistakenly Bombax ceiba is also sometimes called Kopak/kapok tree.

Bombax ceiba is indigenous to South East Asia, while Ceiba pentandra was introduced from South America.

Without knowing even the color of the blossoms we can only guess. And even if we know and the color is "yellow" it will be very difficult.
We need a picture...Otherwise nobody can definitely tell the name of the three.

This is genus Nephila, and certainly a female. Males are much smaller, not to say tiny:

Well, the picture is not very clear…but I assume it is a bagworm, i.e. the caterpillar of a member of the Psychidae family. These caterpillars construct cases in which they live and are often attached to walls etc.

  

  If you can provide a better photo I probably could give more information…

  

  They are absolutely harmless…
